About Cataclysm: Dark Days Ahead

Players explore a persistent, procedurally generated world, scavenge food, equipment and vehicles, secure water and safety, and develop skills for long-term survival while fighting or escaping zombies, giant insects, killer robots and other survivors.

The site hosts downloads with stable 0.I-1 and experimental builds for Windows, Linux, OSX and Android, with terminal and graphical options on Linux and OSX. Tilesets increase RAM use, and the iOS fork is described as very old and unsupported.
